PROCESS OF ORNAMENTING JEWELRY.

SPECIFICATION forming part of Letters Patent No. 360,283, dated March 29, 1887.

Application filed January -2G, 1887.

T0 aZZ whom it may concern.-

Be it known that I, XVILLIAM 0. EDGE, of Newark, in the county of Essex and State of New Jersey, have invented a new and Improved Process of Ornamenting and Decorating Jewelry and other Metal \Vork, of which the following is a full, clear, and exact description.

My invention relates to a process for ornamenting and decorating jewelry and other metal work; and it has for its object to provide jewelry, &c., with a rough and uneven surface, as will be more fully hereinafter described.

In the accompanying drawings, Figure 1 is a view of a piece of metal upon which are placed irregular pieces of copper, embracing the first step of my invention. Fig. 2 is a central sectional view of the same. Fig. 3 is a view similar to Fig. 2, with metal dust or filings applied thereto. Fig. 4: is a central sectional view of a piece of metal after undergoing my process. Fig. 5 is a view of a charm or pendant constructed in accordance with my invention.

A is a piece of metal 011 which my process is to be applied, preferably a piece of gold. Upon this piece of metal I place irregular or other shaped pieces,a,of copper or copper wire in any desired position or quantity. Between these pieces a, I sprinkle filings or dust of gold, silver, or any kind of precious metal desired. These filings or dust are then sweated Serial No. 225.540. (N0 model.)

or melted together, to fill in the spaces between picces, a, of copper or copper wire with solid ridges. The copper is then eaten away by nitric or other acid, leaving the melted filings or dust in ridges c and hollows d of fanciful outline. This gives a pleasing effect to the jewelry, 820., thus decorated.

This process is not limited to the use of flat pieces, A, of metal, but may be applied to anyshapcd article-such, for instance, as the ball 0 in Fig. 5. The filings or dust may be first placed on the metal A and the pieces,a,of copper pressed into the filings, the rest of the operation being performed as described, with the same result. Instead of copper, any other metal easily destroyed by acid may be employed.

Having now described my invention, what I claim is- The herein-described process of decorating jewelry or other metal work, consisting in placing pieces of copper or copper wire soluble in acid upon the metal to be decorated, sprinkling or placing precious metallic filings or dust not soluble in acid upon or around the copper pieces, then sweating or melting the filings together, and removing the copper pieces by eating them away with acid, substantially as described.
